Poltreigh, generally a slow flowing pool with the main current close to the right hand bank. In low to medium water conditions,  0 to 2 feet above low summer level, the fish lie towards this bank As water levels rise the fish tend to move towards the left bank and they can be fished for up to about 5 feet above summer level  provided that the water is reasonably clean.    There are good lies all the way down the pool with several particularly good lies opposite the lowest croy on the right bank where rocks were introduced several years ago.  This pool is very good for fly-fishing even when low, the best fishing being from the left bank, however, because the fish generally lie quite tight to the right bank it is well worth fishing from this side as well.  

Being a slow deep pool makes Poltreigh particulary suited to fishing very early in the season
